As my memory of the actual finale fades, I am beginning to have other interpretations of the finale, mainly on how to look at the time line. I am sure someone has mentioned it before somewhere, but here’s my take.
I don’t remember how blatantly the actual finale stated that Earth is our earth. Because I don’t remember, this is my take…
Earf is our earth. When Tigh went into the water and had all those flash backs, that was a flash back of him in New York city before we destroyed it. So instead of the timeline where we are the descendants of the Hera, skin job cylons are actually descendants of us.
So in the BSG verse we are actually the descendants of the 13th tribe, and the events of BSG happens in our future instead of our past.
I like this version better because it then really makes us think what it means to be human, much better than the finale’s moral of “watch out we are getting close to create cylons”.
Though the problem of course is that none of us refers to ourself as cylons or have any idea how to resurrect into another body (could it be far?).
But that could just be illusion due to my amnesia of the actual finale.
